HEREDITY OF GREEN-BLINDNESS

Blindness in schoolchildren: importance of heredity, congenital cataract, and prematurity.

Of 99 children in the Royal Blind School, Edinburgh (which serves Scotland and part of N E England), 15 had optic atrophy (hydrocephalus 4, intracranial haemorrhage 2, prematurity 2, fetal distress 2, birth asphyxia 2, cerebral atrophy 1, cardiac arrest during hernia operation 1, and leukaemia 1). Fourteen had congenital cataract, 12 congenital retinal aplasia (Leber's congenital amaurosis) and...

Red-green blindness confined to one eye.

We report experimental studies of an individual with different types of color vision in his two eyes. The left eye is typically deuteranomalous, with good wavelength discrimination. The right eye is typically deuteranopic. both in its wavelength discrimination and in its color matching functions. Luminosity curves of left and right eyes are indistinguishable, both being within the normal range....

Gene Therapy for Red-Green Color Blindness

Red-green color blindness, “Daltonism,” is the most common single locus genetic disorder, affecting 6% of men worldwide. Gene therapy is a potential means of correcting the defective or missing locus through the injection/transplantation of a normal transgene. Through the evaluation of one case study, gene therapy has cured colorblindness in squirrel monkeys, and may provide promise for humans.

Some Aspects of Heredity

Hologynic Heredity.

Sex-linked characters in man are well known; they are all pathological characters, so far as known; they are transmitted according to the same laws as the sex-linked characters in the little fruit-fly (Drosophila) and explained in the same manner by means of the sex chromosome. I propose the name “diagynic heredity” for this kind of heredity, as the sex-linked character is transmitted from male...
